    Guys,

    I want to get myself one of the many audi remote 'plip' flip key fobs from ebay and get it programmed to work my remote central locking ( a friend has VAG com and has offered to set this up) however I'm unsure as to which frequency fob I need to get as I dont have the original to check against for part numbers.

    Is there anyway I can find out by using the part number of the central locking pump that is located in the rear drivers side of the car?

    Cheers

    Don't know if it's that simple. My 98 B5 S4 key starts with HLO.

    key fob 2 button part number 4D0 837 231
    3 button part number 4D0 837 231A (will work with 'G' pump but boot release button wont do anything)
    http://cgi.ebay.co.uk/Audi-2-button...3286.c0.m14&_trkparms=66:4|65:1|39:1|240:1318

    better off using an auto locksmith, not dealer, dealers wont give you 4 digit skc so you cant add any more keys yourself with vag com also if transponder wont recode (common with ebay keys) they cant replace it so they'll charge for not being able to programe it

    HL0 part number is for an a3 but will work as a3, a4, a6 and a8's all used the same c/l pumps

    If you need operating frequency, PM me your VIN, and I'll run it through.
